SPECIFICATION forming part of Letters Patent No. 459,670, datedSeptember 15, 1891.

Application filed April 22, 1891. Serial No. 889,973. (No model.)

To all whom it may concern:

Be it known that I, CLARENCE L. BARN- HART, of Flint, in the county ofGenesee and State of Michigan, have invented a new and ImprovedBaby-Jumper, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide an efiicient spring-actuatedbaby-j umper simple and durable in construction and effective inoperation.

The invention consists in the novel c011- struction and combination ofparts, as hereinafter particularly described, and defined in the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a perspective view of a babyjumper embodying my inventionand Fig. 2 is a detail end view of the crib and aportion of itssupporting-hanger. In constructing a baby-j umper embodying my inventionI provide a base A of skeleton form, comprising a front bar a and theside bars a, the same being provided with a suitable number of castersBto enable the jumper to be readily moved from place to place, asdesired. At the rear end the side bars a of the base A are projectedupwardly and inwardly, as at (1- the upper meeting ends being welded orriveted to and serving to support a standard A. At its upper end thestandard A extends forwardly to form the overhanging arm A the extremeouter end of which lies in about the horizontal plane and terminates inan eye or ahook a From the outer end of the arm A as thus formed thehanger C, having an eye 0 at its upper end, is suspended through themedium of a spring D of novel construction, the crib E being held on thehorizontally-ranginglower end 0 of the hanger C.

The crib E is preferably made of light or thin material, and that it maybe thus made the connection with the arm 0 is effected through themedium of a screw or screws F, passing through a block E, or anequivalent enlargement, interposed between the arm 0 and the bottom ofthe crib, the said block or its equivalent thus serving to strengthenthe connection at the point of strain.

The spring D is of the spiral variety and is formed of two strands ofwire cl d, the terminals of which are joined to form loops d at the endsof the spring, which engage the eye (63 of the standard and the eye 0 ofthe hanger. lVith this form of spring increased strength and increasedelasticity is obtained, and the crib will be kept in motion for anincreased length of time.

The casters B on the base enable the jumper to be moved about with ease,and the whole structure is light, durable, and efficient and involves acomparatively small cost in its manufacture.

By the term crib as herein used I mean any device for holding orsupporting the child, such as a chair, a frame, or straps for holdingthe child.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a baby-jumper, the base A, having the front cross-bar a and havingits side arms a continued inwardly and upwardly to form the standard A,the said standard overhanging at its upper end, as at A aspiral springD, suspended from said overhanging end, ahangerarm C, suspended fromsaid spring and formed with arigid horizontal seat which extends and issupported at one side of said hanger-arm, and a crib E, secured to saidhorizontal seat, all in combination substantially as described.
